Two-factor authentication, known as 2FA, is a security method that helps protect your online accounts. It requires two forms of verification before you can log in, which makes it much harder for hackers to access your accounts, even if they have your password. Here we help you understand how 2FA works and why it’s important.
How 2FA Works
Normally, logging in to an account requires only a password. With 2FA, you need a second step. This second factor can be:
- Something you have: like on your smartphone or a security token.
- Something from you: like your fingerprint or face.
For example, after entering your password, a website might send a code to your phone. You then need to enter that code to finish logging in. Remember, always use a backup method in case your phone or device is lost.
Common Types of 2FA
- SMS Codes: A code is sent via text message to your phone.
- Authenticator Apps: Apps are used to generate temporary codes.
- Hardware Tokens: Physical devices, like a USB key, will generate a code or plug into your computer.
- Biometric Verification: Fingerprints, facial recognition or voice recognition.
Many small businesses protect their accounts using website security checks, like those at //www.etempa.co.uk/website-security-checks/, to keep information safe.
Why 2FA Is Important
Passwords can be stolen, guessed or leaked. 2FA provides more security. Even with your password, a hacker cannot usually log in without the second factor. This is especially important for email, banking, social media and gaming accounts where all your sensitive data is stored.
